Abstract
A device is described for storing, and periodically announcing the time for removal of, drug doses in pill, tablet or capsule form. A patient is warned at regular intervals to remove a drug dose from a blister pack serving as drug container. An electronic timer system associated with the blister pack activates periodically a signal emitter which emits a preferably acoustic signal. Optionally an optical signal emitter can also be installed in the warning ystem. The system comprises an electrically activatable input which receives a starting pulse at the time when a first drug dose is to be removed from the blister pack. The starting pulse is generated by rupturing, through removal of a drug dose from a blister pocket, an electric pulse lead which extends across the blister pocket in the rupturable closing foil of the latter and which is connected to the starting pulse input of the timer in the warning system.
